ipa: raspberrypi: Ensure shutter speed and gain are clipped in the AGC

Make a copy of the CameraMode structure on a switch mode call. This replaces the existing lastSensitivity_ field. Limit the AGC gain calculations to the minimum value given by the CameraMode structure. The maximum value remains unclipped as any gain over the sensor maximum will be made up by digital gain. Rename clipShutter to limitShutter for consistency, and have the latter limit the shutter speed to both upper and lower bounds.
